Installing microceph charm removes symlinks to block devices

[Marian Gasparovic]

Before charm is installed

ll /dev/disk/by-dname/
lrwxrwxrwx 1 root root 13 Sep 27 08:55 disk0 -> ../../nvme0n1
lrwxrwxrwx 1 root root 15 Sep 27 08:55 disk0-part1 -> ../../nvme0n1p1
lrwxrwxrwx 1 root root 15 Sep 27 08:55 disk0-part2 -> ../../nvme0n1p2
lrwxrwxrwx 1 root root 15 Sep 27 08:55 disk0-part3 -> ../../nvme0n1p3
lrwxrwxrwx 1 root root 13 Sep 27 09:59 disk1 -> ../../nvme1n1
lrwxrwxrwx 1 root root 13 Sep 27 08:54 nvme2n1 -> ../../nvme2n1
lrwxrwxrwx 1 root root 13 Sep 27 08:54 nvme3n1 -> ../../nvme3n1
lrwxrwxrwx 1 root root 9 Sep 27 08:54 sda -> ../../sda
lrwxrwxrwx 1 root root 9 Sep 27 08:54 sdb -> ../../sdb
lrwxrwxrwx 1 root root 9 Sep 27 08:54 sdc -> ../../sdc

After charm is installed

ll /dev/disk/by-dname/

lrwxrwxrwx 1 root root 15 Sep 27 10:06 disk0-part1 -> ../../nvme0n1p1
lrwxrwxrwx 1 root root 15 Sep 27 10:06 disk0-part2 -> ../../nvme0n1p2
lrwxrwxrwx 1 root root 15 Sep 27 10:06 disk0-part3 -> ../../nvme0n1p3
lrwxrwxrwx 1 root root 9 Sep 27 10:06 sda -> ../../sda
lrwxrwxrwx 1 root root 9 Sep 27 10:06 sdb -> ../../sdb
lrwxrwxrwx 1 root root 9 Sep 27 10:06 sdc -> ../../sdc

Not a one-off event, this is happening on this server every single time.

It works fine with microceph snap, fails only when charm is used.
