What I did
The bug can be reproduced by the following command:
root@bjw-can-7215-6:/home/admin# sonic-installer set-fips
Command: /usr/bin/fw_setenv linuxargs net.ifnames=0 loopfstype=squashfs loop=image-fips-armhf-202305.88981472-dde4d1d844/fs.squashfs systemd.unified_cgroup_hierarchy=0 varlog_size=4096 loglevel=4 logs_inram=on sonic_fips=1
Error: illegal character '=' in variable name "loopfstype=squashfs"
How I did it
It is to set the variable linuxargs to the the environment value cmdline, as the part of the Linux Kernel Cmdline. The environment variable cannot be split.
