Check if at least 100Mib of available space on /boot. If not, inhibit the upgrade process.
Rationale for the requirement of 100MiB:
- Before reboot into initramfs, the CopyInitramfsToBoot actor copies kernel and initramfs to
/boot, together worth of 66MiB.
- After booting into initramfs, the RemoveBootFiles actor removes the copied kernel and
initramfs from /boot.
- The DnfShellRpmUpgrade installs a new kernel-core package which puts additional 54MiB of data
to /boot.
- Even though the available space needed at the time of writing this actor is 66MiB, the
additional 100-66=34MiB is a leeway for potential growth of the kernel or initramfs in size.
