Instead, either use the bash built-in of type to ensure it exists. Since which is an external dep, things can fail oddly in a constrained environment. Also add a dib-lint test for this. Change-Id: I645029f5b5bfe1198c89ce10fd3246be8636e8af Signed-off-by: Jesse Keating <omgjlk@us.ibm.com>

# NOTE(bnemec): Workaround for bug in Dracut. This fix has been proposed to

# Dracut as well in https://github.com/haraldh/dracut/pull/34 , and once it has

# been released for all of our supported platforms we can remove this. Until then

# Dracut version.

# Notes on the options passed to Dracut:
|
|
# -N: Do not build a host-specific ramdisk. We want to be able to run this ramdisk
|
|
# on as many different machines as possible.
|
|
# --install: A list of the binaries needed by our ramdisk script fragments.
|
|
# --kernel-cmdline: Kernel parameters to pass to the ramdisk. rd.neednet is required
|
|
# to force Dracut to bring up networking even if it isn't passed a
|
|
# network target root. Pre-loading the ahci module is necessary
|
|
# on some systems to ensure that SATA disks are recognized.
|
|
# --include: Files from the chroot to include in the ramdisk.
|
|
# --kver: The kernel version to use, as determined above.
|
|
# --add-drivers: Extra kernel modules to include in the ramdisk.
|
|
# -o: Force omission of these dracut modules. Our scripts are written for bash,
|

# so dash is not desirable, and plymouth was causing some issues on Ubuntu.
