Debian 10: two encrypted disks with one password - entered only once?
by JacekZ from LinuxQuestions.org on (#4SCF4)
Hi folks
I installed buster on one encrypted drive using the built in installer, and later added another one using:
- cryptsetup and
- mount
and by editing
- /etc/crypttab and
- /etc/fstab
I gave both encrypted drives the same passphrase
Buster's installation guide 7.2 says:
"you will be asked to enter the passphrase for each of these volumes during the boot"
So i'd expect to enter the passphrase twice, and indeed, this stackexchange item says how you have to work around things to only have to enter the password once.
But what's happening is that I only have to enter the password once with no work-around required.
At risk of sounding like complaining that this is too good to be true, does anyone know how this is possible? Have I done something wrong? Has Buster been improved in some undocumented way / documented somewhere else? I've done quite a bit of reading around this and can find nothing to explain.
Thanks.
