Subject: [PATCH] convert_linux: extract qemu-guest-agent package name
|
|
|
|
In commit a30383e35d34 ("v2v: linux: do not install qemu-guest-agent if
|
|
already installed", 2019-09-20), the name of the package providing the
|
|
QEMU guest agent was hard-coded as "qemu-guest-agent", regardless of
|
|
distro family. Turns out this is actually correct (and may have been
|
|
intentional, only it was not specifically documented): in all OS families
|
|
currently recognized by our "family" function (`RHEL_family, `ALT_family,
|
|
`SUSE_family, `Debian_family), the *binary* package is indeed called
|
|
"qemu-guest-agent":

|
|
- https://packages.debian.org/search?keywords=qemu-guest-agent&searchon=names&suite=all§ion=all
|
|
|
|
As a way of documenting this, extract the mapping to a new helper function
|
|
named "qga_pkg_of_family".
