Create custom profiles

Gentoo Profiles

创建一个repo配置文件内容如下(/etc/portage/repos.conf/local.conf)

cat << EOF > /etc/portage/repos.conf/local.conf
[local]
# 'eselect repository' default location
location = /var/db/repos/local
EOF

设置repo名(/var/db/repos/local/profiles/repo_name)

mkdir -p /var/db/repos/local/{profiles,metadata}
echo "local" > /var/db/repos/local/profiles/repo_name

设置layout(/var/db/repos/local/metadata/layout.conf)

cat << EOF > /var/db/repos/local/metadata/layout.conf
# Slave repository rather than stand-alone
masters = gentoo
profile-formats = portage-2
EOF

假设x11-terms/st在当前profile下是没有设置如下use的,现在想在新的profile中默认配置这个use

equery u x11-terms/st
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for x11-terms/st-9999:
 U I
 - - savedconfig : Use this to restore your config from
				   /etc/portage/savedconfig ${CATEGORY}/${PN}. Make sure
				   your USE flags allow for appropriate dependencies

配置需要修改的use

cd /var/db/repos/local/profiles
mkdir savedconfig && echo 7 > savedconfig/eapi
echo "x11-terms/st savedconfig" > savedconfig/package.use

创建custom目录

profile_name=custom
mkdir $profile_name && echo 7 >$profile_name/eapi
cat << EOF > $profile_name/parent
gentoo:default/linux/amd64/17.0
../savedconfig
EOF

创建profile.desc文件

echo `portageq envvar ARCH` $profile_name dev >>profiles.desc

现在就可以查看到自己创建的profile了

eselect profile list

Available profile symlink targets:
  ...
  [88]  local:custom (dev)

选择使用这个自定义的profile

eselect profile set 88

再次查看之前配置的软件use情况和之前不一样了

equery u x11-terms/st
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for x11-terms/st-9999:
 U I
 + - savedconfig : Use this to restore your config from
				   /etc/portage/savedconfig ${CATEGORY}/${PN}. Make sure
				   your USE flags allow f`
