Since yum is >invoked by preupgrade, the operation can be aborted via a \fBNo\fR response >to the \fB"Is this ok [y/N]:"\fR question. > >If \fBno options\fR are provided, then \fBpreupgrade\fR displays a list of >possible release names that are available to upgrade an existing distribution >to. The number of releases available depends on where the existing system >is in the Fedora release cycle. For example, a Fedora 6 system may have a >Fedora 7, Fedora 8, Fedora 9 and Rawhide release available right after Fedora 9 >has been released. Please remember that Fedora 7 would shortly be at its >end of life, EOL, in this example once Fedora 9 has reached general >availability, GA. > >\fBpreupgrade\fR was designed to leave the system administrator in control. >A grub menu item is created to launch the upgrade. However, \fBpreupgrade\fR >leaves your last working kernel installation as the default grub menu item. >The grub menu entry will be named something similar to >\fB"Upgrade to Fedora X (release name)"\fR where \fBX\fR is the Fedora release >number and \fB(release name)\fR may be something simliar to "Sulphur". >You may modify the stock grub menu entry created by \fBpreupgrade\fR. You >may need to add additional configuration options before rebooting your >system. Some ideas include a kickstart file, ks.cfg, video, or other >options required by your hardware or installation environment. >grubby is invoked to create the /boot/grub/grub.conf menu entry. > >.PD >.SH NOTES >If \fBpreupgrade\fR is interrupted, then it will resume the downloads where >it left off. > >Make sure that you have enough disk space allocated to your /var partition, >if you have placed /var on another disk or file system. \fBpreupgrade\fR >will use the /var/cache/yum directory to download other support files. > >Likewise, your /boot partition needs enough disk space to store another >vmlinuz compressed kernel file and two image files. > >.PD >.SH "RETURN CODES" >\fBpreupgrade\fR returns 0 on success, 2 on error. > >.PD >.SH FILES >.PD 0 >.TP >.TP >.FN /etc/grub.conf or >.FN /boot/grub/grub.conf >\fBpreupgrade\fR modifies the existing system's grub menu providing an entry to invoke the upgrade after rebooting the system. >.TP >.FN /var/cache/yum >\fBpreupgrade\fR uses the /var/cache/yum directory to stage the upgrade files. >An anaconda-upgrade directory is created under the /var/cache/yum directory >to hold and organize the related release files. >.TP >.FN /boot/upgrade >The /boot/upgrade directory is used to store the three files used to >launch the upgrade.
