Mount filesystems

Mount filesystems. Use <code>lsblk -o +uuid,fsType | grep bcachefs</code> to get bcachefs partition uuid.

~~There are two ways~~ to ~~mount a~~ bcachefs ~~filesystem~~. ~~First, by device:~~

# mount /dev/~~sda2~~ /mnt

# mount /dev/disk/by-uuid/<...> /mnt

# mkdir /mnt/boot

# mount /dev/disk/by-label/boot /mnt/boot

</syntaxhighlight>

~~For better reliability as with any other filesystem, one should mount the filesystem by UUID, by replacing any drive specifiers with it.~~

~~When you formatted, there was an external UUID shown, but if you lost it, you can retrieve it using~~

~~<syntaxhighlight lang="console">~~

~~# lsblk -o +uuid,fsType | grep bcachefs~~

~~</syntaxhighlight>~~

~~And using it like <code>UUID=<UUID></code> in place of <code>/dev/sda1:/dev/sdb1</code> or even just <code>/dev/sda</code>.~~
