Except that for many years installing has collected all discoverable swap partitions, and put them into /etc/fstab for use as swap. This has resulted in time bombs. I often have one swap partition per spindle, exactly so that any OS with a root on another spindle still will run when a drive fails. Systemd has changed the way things work: an "absent" swap partition now causes a mysterious 90-second timeout at boot, which looks like an unexplained failure.

NO! NO! Do NOT format any partition, including swap partitions, except when explicitly requested. I want to share _some_ swap partitions, but running mkswap destroys the UUID and/or label which other /etc/fstab depend on. In particular, I want to share the swap partition as the primary swap partition for all OS on the same drive. For better performance I'll allow using the swap partitions on other drives. But I don't want the "temporary" non-appearance of a swap partition on some other drive to interfere with booting when the swap partition on the same drive is working fine.

Some of that change is good, but on a box with only one drive I should be able to install another OS which shares the same swap partition [on that drive] without having to edit /etc/fstab later, and without having the installer re-format the shared swap partition unless I explicitly request that. -- -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
