Programs in these directories (called hooks) are combined
and executed in C sort order before suspend and hibernate
with as argument ´suspend´ or ´hibernate´. Afterwards they
are called in reverse order with argument ´resume´ and
´thaw´ respectively. If both directories contain a similar
named file, the one in /etc/pm/sleep.d will get preference.
It is possible to disable a hook in the distribution
directory by putting a non-executable file in
/etc/pm/sleep.d, or by adding it to the HOOK_BLACKLIST
Thus you could simply put a shell-script like this:
case "$1" in
99-myhooks.sh and make it executable.
BTW, you can kill stale SSH-connections by entering Enter~.Enter in the SSH session.
