We are currently using an USB stick with autodiscover functionality.
Occasionally, the installation (Debian bookworm) goes to the USB stick
instead of the internal disk.
This is from fai-disk-info:
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
checkdisk() {
while read major minor blocks device suffix; do
isdisk=1
# skip ide cdrom
[ -f /proc/ide/$device/media ] && grep -q cdrom
/proc/ide/$device/media && isdisk=0
# old way of detecting disks: [ `cat /sys/block/$device/removable` -eq 1
] && isdisk=0
[ `stat -c %G /dev/$device` = "disk" ] || isdisk=0
During the installation, both the USB stick and the internal SSD is
owned by root:disk, so the USB stick is not skipped here.
As expected, /sys/block/sd*/removable reads '1' for the USB stick and
'0' for the SSD.
What is the advantage of checking the device group instead of the
removable flag in /sys here anyway?
