Security is nearly zero in such a constellation. Passphrase-based decryption is good as long as you have physical access to the server and only you (and maybe those you trust) have a secure (!!!) password which needs to be entered manually at system startup to "unlock" the /home drive or partition. > >> q) The second laptop has an SSD, would UFS with/without J and > >> with/without SU or ZFS make more sense for it? > > > > There are several parameters that you can tweak (see "man tunefs"), > > I would suggest a single partition spanning the whole SSD, and > > journaling would not be contraproductive. > > s/would not/would/ > i assume this as mistake. do not journal on SSD. it increases amount of > writes, and fsck is quick anyway. Good you spotted it - of course there is no need for journaling in this case (too much writes, no real benefit). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
