Description of problem: Device names written to /etc/fstab and /etc/zipl.conf during installation on s390x are not persistent: fstab: /dev/dasdc1 / xfs defaults 0 0 /dev/dasda1 /boot ext4 defaults 1 2 /dev/dasdb1 swap swap defaults 0 0 $ cat zipl.conf | grep root= parameters="root=/dev/dasdc1 cio_ignore=all,!condev rd.znet=qeth,0.0.0a00,0.0.0a01,0.0.0a02,layer2=1,portno=0,portname=FOOBAR LANG=en_US.UTF-8" parameters="root=/dev/dasdc1 cio_ignore=all,!condev rd.znet=qeth,0.0.0a00,0.0.0a01,0.0.0a02,layer2=1,portno=0,portname=FOOBAR" $ Since the names of the devices can change each reboot, the system often doesn't boot. Persistent names/UUIDs/LABELs should be used instead. Version-Release number of selected component (if applicable): anaconda-25.20.1-1.fc25 python3-blivet-2.1.2-1.fc25 How reproducible: always on s390x Steps to Reproduce: 1. proceed through text mode installation on s390x, use standard disk layout (without LVM/RAID) 2. before rebooting check /mnt/sysimage/etc/fstab and /mnt/sysimage/etc/zipl.conf Actual results: Names /dav/dasd* used Expected results: Persistent names used (or UUID/LABEL) Additional info: I cannot reproduce it on x86_64, where partitions are referenced using their UUIDs, for example: [root@localhost ~]# grep /boot /etc/fstab UUID=e4fffa90-384e-4d3a-955b-162dfb8c139a /boot ext4 defaults 1 2 [root@localhost ~]#

Retested on compose Fedora-25-20161007.0 with updates=http://fedora.danny.cz/s390/updates-1378338.img and I cannot reproduce it any longer: [root@rtt7 ~]# cat /proc/cmdline root=/dev/disk/by-path/ccw-0.0.3027-part1 rd.dasd=0.0.3027 rd.dasd=0.0.3127 rd.dasd=0.0.3527 cio_ignore=all,!condev rd.znet=qeth,0.0.0a00,0.0.0a01,0.0.0a02,layer2=1,portno=0 LANG=en_US.UTF-8 BOOT_IMAGE=0 [root@rtt7 ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Thu Oct 13 09:59:43 2016 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/disk/by-path/ccw-0.0.3027-part1 / xfs defaults 0 0 /dev/disk/by-path/ccw-0.0.3127-part1 /boot ext4 defaults 1 2 /dev/disk/by-path/ccw-0.0.3527-part1 swap swap defaults 0 0 [root@rtt7 ~]# So, I'm closing this bug for now.
