Ok, this is weird as hell
13:31
<&ToxicFrog>
I can't mount /boot
13:31
<&ToxicFrog>
No error message, strace shows that `mount(2)` returns successfully, it just doesn't get mounted
13:31
<&ToxicFrog>
Nothing in dmesg
13:32
<&ToxicFrog>
If I pick a different mountpoint for the same filesystem, it works
13:33
<@TheWatcher>
O.o
13:33
<@TheWatcher>
That is bloody odd
13:38
<&ToxicFrog>
I can't mount it somewhere else and then `mount -o bind` it into place, either.
13:42
<@abudhabi>
Reboot?
13:43
<&ToxicFrog>
If something is wrong with /boot rebooting may not work
13:43
<&ToxicFrog>
As in, may not boot
13:45
<@abudhabi>
Got a boot medium handy?
13:53
<&ToxicFrog>
I've got a liveUSB I can boot from if needed, but I would really like to avoid extended downtime on ancilla if possible
14:15
<&ToxicFrog>
Problem solved: it had previously had another drive connected with the same label and fstab was by-label, confusing it
14:20
<&ToxicFrog>
Forcing to reread the partition table and filesystem signatures with fdisk fixed it.,
14:24
<@TheWatcher>
\o/

<@TheWatcher>
That's a relief

<ToxicFrog> If something is wrong with /boot rebooting may not work <-- actually that won't matter
16:25
<&[R]>
Your bootloader doesn't mount /boot, but has access to it regardless, you've confirmed the FS is fine
16:26
<&[R]>
After the initrd mounts / you don't need access to /boot for any of the remaining boot process (you actually don't need it once the initrd is loaded into memory)
17:38
<&ToxicFrog>
It's more that without the ability to update /boot there is no guarantee that any of the generations the bootloader is aware of correspond to ones that still exist on /

What bootloader are you using that cares about things outside of /boot and the MBR/EFI?

[R]: the bootloader is grub2 and it doesn't care, but it tells the initrd which view of / to load and the initrd cares a great deal about things like /etc actually existing
22:52
<&ToxicFrog>
Earlier I didn't know how long /boot had been in this unmountable state, so it was possible that the bootloader config on it only contained entries for generations that had been GCed since
