[gentoo-user] dmcrypt for a /home directory that already has many files on it
I was planning to use dmcrypt on my /home partition and I read the proceedure on the Gentoo Wiki. I think though, that the proceedures given there are for new partitions without a filesystem. Maybe I am wrong. Anyway, I wondered if there would be any problem with temporarily moving my /home data to some new directory on /usr, then using the dmcrypt on the /home directory, and finally copying all of the old /home data back onto the new encrypted partition?

I was planning to use dmcrypt on my /home partition and I read the proceedure on the Gentoo Wiki. I think though, that the proceedures given there are for new partitions without a filesystem. Maybe I am wrong. I didn't read it, but if this encryption crypts a complete partition, then I'd like to recommend to better use a crypted loopback mounted file. The reason is backup: In the latter case you can simply compress the crypted container and back it up - it is still crypted. I did it this way some time ago and found it very convenient. Anyway, I wondered if there would be any problem with temporarily moving my /home data to some new directory on /usr, then using the dmcrypt on the /home directory, and finally copying all of the old /home data back onto the new encrypted partition? Put it in a tarball preserving all file attributes (ownership and other flags) and untar it into the crypted container after mounting it. Best regards ce -- gentoo-user@gentoo.org mailing list

A very good idea i.e. the tar file. Rob -- gentoo-user@gentoo.org mailing list
