Description of problem: Here's how my fat32 flash drive gets mounted: /dev/sdb1 on /run/media/birdie/USB type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2) Version-Release number of selected component (if applicable): storaged-2.6.2-2.fc25.x86_64 Here's what's wrong with these mount options: "flush" is only good for people with OCD and at the same time it makes random small writes to the disk several magnitudes of order slower because most USB flash disks have very bad small IO thoughput. codepage=437 works only for countries where English is an official language and locale on their Windows PCs. For instance in Cyrillic speaking countries codepage must be 866. iocharset must be utf8 for all intents and purposes. There's no "quite" option which I'd love to see because it silences `cp -a` errors in regard to setting the owner/group. There's no "usefree" option which increases mount speed by several orders of magnitude because the kernel doesn't have to scan all free sectors. I would love to see "noatime" because I don't care about access times on my slow USB storage. Please, make it possible to change all mount options aside from uid=$USERID,gid=$GROUPID
> "flush" is only good for people with OCD and at the same time it makes random small writes to the disk several magnitudes of order slower because most USB flash disks have very bad small IO thoughput. I'm really not sure why this is in the default mount options. We should probably remove it. > codepage=437 works only for countries where English is an official language and locale on their Windows PCs.

These are default values from kernel config: CONFIG_FAT_DEFAULT_CODEPAGE=437 CONFIG_FAT_DEFAULT_IOCHARSET="ascii" But it is possible to specify your own values for these options when mounting using storaged. > There's no "quite" option which I'd love to see because it silences `cp -a` errors in regard to setting the owner/group. > I would love to see "noatime" because I don't care about access times on my slow USB storage. > There's no "usefree" option which increases mount speed by several orders of magnitude because the kernel doesn't have to scan all free sectors. You can specify extra options for Mount function -- you can set the "usefree" and "noatime" options if you want (not sure why not "quiet").

I wonder if it has to do with this insight from Lennart (reddit comment link) where he says (in my words) that systemd's mount system is intended to not mount a USB drive before it is needed an unmount it as soon as possible. https://www.reddit.com/r/linux/comments/4ypb2g/systemd_rolls_out_its_own_mount_tool/d6qicwi/ > We don't add these options in storaged.

Where is that done? A particular unit in /etc/systemd/system to be over-ridden in /etc/systemd/user ?

(In reply to Vojtech Trefny from comment #1) > We don't add these options in storaged. These are default values from kernel config These two options are default yet perfectly overridable and should be overridden for all countries where the default (Windows) locale is not English (CP437). > But it is possible to specify your own values for these options when mounting using storaged. That's exactly what this bug is about. I would love to be able to configure (add/remove/change) pretty much all the options which are used for mounting removable storage. Also this bug is not about fat32/vfat per se, it's about all other filesystems as well. Like I said 99.9% of users will never need last access time updated on their removable storage, besides this operation involves a lot of small writes and seeks and it's specially "bad" for usual USB sticks. > You can specify extra options for Mount function -- you can set the "usefree" and "noatime" options if you want (not sure why not "quiet"). Again my question is how. I cannot find anything remotely relevant in Fedora documentation. Even Arch Linux Wiki is very light on details. In the past, when we had HAL, I did this: cat /etc/hal/fdi/policy/20-fs_options.fdi <?xml version="1.0" encoding="UTF-8"?> <deviceinfo version="0.2"> <device> <match key="volume.fstype" string="ntfs"> <append key="volume.mount.valid_options" type="strlist">uid=1000,fmask=0133,dmask=0022,nls=utf8,rw</append> </match> <match key="volume.fstype" string="vfat"> <append key="volume.mount.valid_options" type="strlist">noatime,showexec,iocharset=utf8,uid=1000,gid=1000,codepage=866,fmask=0111,dmask=0000,umask=0000,quiet,usefree,shortname=mixed</append> </match> </device> </deviceinfo> Nowadays it's absolutely moot. Should I use GUI tools? Or should I try creating certain files in /etc? What about making system wide changes so that if I have 10 user accounts on my PC I will not have to configure this for every user? Then again and I'm asking it for the third time, the user must have an option to 1) add 2) change 3) remove ***all*** the options for their removable storage. In fact Fedora should allow me to mount removable media without ***any*** options whatsoever (e.g. /dev/sdb1 on /media/flash type ext4 (rw)). This is what this bug is about. Your defaults and even kernel defaults may not work for some people and for other people these options might be dealbreakers which hamper their workflow. (In reply to Vojtech Trefny from comment #3) > "flush" was added because of this bug -- https://bugs.freedesktop.org/show_bug.cgi?id=51063 -- so at least some people think it should be default. If people knew they could in fact remove their storage properly by using "Eject" and at the same time gained quite tangible performance increases, the overall feeling would be to make this option configurable. I'm not against of having it by default for the reckless, but other people might enjoy a different scenario.
