glibc is special.

When glibc is updated it executes from %post

/usr/sbin/glibc_post_upgrade.x86_64

which severely lacks documentation, best I could find

is it runs

telinit u; service sshd condrestart


It definitely does restart crond I'm sure since a few years back it wend 
bad and crond failed across the whole plant.

Not sure I actually trust the above to actually restart everything.
