in install_dependent_modules we use &path[kerneldirlen] as the key for inserting, let's do the same for checking. otherwise installing kernel module has circular dependency from a custom kernel module directory will cause infinite recursion and segfault. $ grep ipmi kbuilt/lib/modules/5.10.121/modules.dep kernel/drivers/char/ipmi/ipmi_msghandler.ko: kernel/drivers/char/ipmi/ipmi_devintf.ko: kernel/drivers/char/ipmi/ipmi_msghandler.ko $ grep ipmi kbuilt/lib/modules/5.10.121/modules.softdep softdep ipmi_msghandler post: ipmi_devintf $ ./dracut-install -D /tmp --kerneldir ~/working/kernel/linux-5.10.121/kbuilt/lib/modules/5.10.121 -m ipmi-devintf Segmentation fault (core dumped) (gdb) b install_dependent_modules Breakpoint 1 at 0x7db0: file src/install/dracut-install.c, line 1513.

Hi , I have verified that livenet with a rootfs with ext2 format works well, it use curl to download real rootfs.
Can you add a feature to detect if compressed image? if yes , add a decompress step before switching root.
Thank you!
