[pve-devel] [PATCH kernel-meta 09/10] efiboot: only keep last two series metapackages

[Fabian Grünbichler]

namely, the current/latest and previous one, for which we also keep the
last kernel installed and synced.

the pipe to 'head' has the added bonus of guarding against 'grep'
returnin non-zero and triggering 'set -e'
