Sock­ets and nullfs: works now in –cur­rent

I just up­dated to a re­cent -cur­rent and tried the new nullfs. Sock­ets (e.g. the MySQL one) work now with nullfs. No need to have e.g. jails on the same FS and hard­link the socket to not need to use TCP in MySQL (or an IP at all for the jail).

Great work!

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.
