Subject: [PATCH] fix(dracut.sh): harden dracut against GZIP environment
|
|
variable

When a GZIP environment variable is set, this leads to various breakage:
|
|
|
|
In case 'pigz' is installed and GZIP is defined as a path, e.g.
|
|
/usr/local/bin/gzip, then dracut will fail with the following message:
|
|
|
|
"
|
|
pigz: abort: cannot provide files in GZIP environment variable
|
|
"
|
|
|
|
In case 'pigz' isn't installed and regular 'gzip' is used and GZIP is
|
|
defined as a path, e.g. /usr/local/bin/gzip, then the path will be
|
|
zipped and dracut will fail for no obvious reason. Trying again, dracut
|
|
will then fail with following message:
|
|
|
|
"
|
|
gzip: /usr/local/bin/gzip.gz already exists; not overwritten
|
|
"
|
|
|
|
In any case, GZIP environment should be unset to avoid breakage or
|
|
unwanted behaviour. This variable is anyway obsolescent, from gzip(1)
|
|
manpage.
