Hint: using sock­ets across jails

I want to use a socket (mysql) in mul­ti­ple jails. Using nullfs to mount it in each jail where you want to use it does not work (bug in nullfs?). Using a hardlink (if the jails reside on the same FS) works. I hope this info safes a lit­tle bit of time in case some­one tries to do the same.

The host­name MySQL sees in such a con­nec­tion is “local­host”. Maybe this is obvi­ous to one or another, but because jails don’t have a 127.0.0.1 it was not obvi­ous to me.
