Support booting from devices exposed as non-removable
Tails refuses to boot from devices that expose themselves as non-removable:
Some USB sticks (especially Sandisk) expose themselves as non-removable.Not the case anymore: #16926 (closed)
- Some external USB hard drives and SSDs expose themselves as non-removable.
- There’s recurring interest in installing Tails on internal hard disks (e.g. for performance reasons, or to dedicate a machine to Tails, or to avoid having a USB stick protruding outside of a laptop, or to install Tails on a tablet’s internal storage): see #8422 for use cases and what it would take to support it.
A plan could be to:
pass the syslinux SYSAPPEND variable a bitmask that enablesDONE in d421f38e
FSUUID=functionality (bit 0x40000): this feature appends, to the kernel command-line, the UUID of the partition the kernel is booted from (added in 6.03-pre9, see commit 386b59e1 in syslinux Git)
- add support to live-boot to search the SquashFS only on the
filesystem specified by the FSUUID kernel command-line parameter,
when present; when present, FSUUID should override any
live-media=found on the command-line, so that we would still pass
live-media=removable, that would only be taken into account when booting from DVD.
