Subject: [PATCH] kernel-install: avoid process substitution
Kevin Fenzi 1eb707
Kevin Fenzi 1eb707
bash implements process substitution using /dev/fd/N (this is documented
Kevin Fenzi 1eb707
in man bash). We'd like kernel-install to work in chrooted RPM
Kevin Fenzi 1eb707
scriptlets without /dev.
Kevin Fenzi 1eb707
Kevin Fenzi 1eb707
We can use here-strings instead. bash uses temporary files to implement
Kevin Fenzi 1eb707
those.
