If '._cfg0000_foo' already exists, this name becomes -'._cfg0001_foo', etc. In this way, existing files are not overwritten, -allowing the administrator to manually merge the new config files and avoid any -unexpected changes. - -In addition to protecting overwritten files, Portage will not delete any files -from a protected directory when a package is unmerged. While this may be a -little bit untidy, it does prevent potentially valuable config files from being -deleted, which is of paramount importance. - -Protected directories are set using the CONFIG_PROTECT variable, normally -defined in /etc/make.globals. Directory exceptions to the CONFIG_PROTECTed -directories can be specified using the CONFIG_PROTECT_MASK variable. To find -files that need to be updated in /etc, type: - -# find /etc -iname '._cfg????_*' - -You can disable this feature by setting CONFIG_PROTECT="-*" in /etc/make.conf. -Then, Portage will mercilessly auto-update your config files. Alternatively, -you can leave Config File Protection on but tell Portage that it can overwrite -files in certain specific /etc subdirectories. For example, if you wanted -Portage to automatically update your rc scripts and your wget configuration, -but didn't want any other changes made without your explicit approval, you'd -add this to /etc/make.conf: - -CONFIG_PROTECT_MASK="/etc/wget /etc/rc.d" - -Tools such as dispatch-conf, cfg-update, and etc-update are also available to -aid in the merging of these files.

The purpose of +this feature is to prevent new package installs from clobbering existing +configuration files. By default, config file protection is turned on for /etc +and the KDE configuration dirs; more may be added in the future. + +When Portage installs a file into a protected directory tree like /etc, any +existing files will not be overwritten. If a file of the same name already +exists, Portage will change the name of the to-be-installed file from 'foo' to +'._cfg0000_foo'. If '._cfg0000_foo' already exists, this name becomes +'._cfg0001_foo', etc. In this way, existing files are not overwritten, +allowing the administrator to manually merge the new config files and avoid any +unexpected changes. + +In addition to protecting overwritten files, Portage will not delete any files +from a protected directory when a package is unmerged. While this may be a +little bit untidy, it does prevent potentially valuable config files from being +deleted, which is of paramount importance. + +Protected directories are set using the CONFIG_PROTECT variable, normally +defined in /etc/make.globals. Directory exceptions to the CONFIG_PROTECTed +directories can be specified using the CONFIG_PROTECT_MASK variable. To find +files that need to be updated in /etc, type: + +# find /etc -iname '._cfg????_*' + +You can disable this feature by setting CONFIG_PROTECT="-*" in /etc/make.conf. +Then, Portage will mercilessly auto-update your config files. Alternatively, +you can leave Config File Protection on but tell Portage that it can overwrite +files in certain specific /etc subdirectories. For example, if you wanted +Portage to automatically update your rc scripts and your wget configuration, +but didn't want any other changes made without your explicit approval, you'd +add this to /etc/make.conf: + +CONFIG_PROTECT_MASK="/etc/wget /etc/rc.d" + +Tools such as dispatch-conf, cfg-update, and etc-update are also available to +aid in the merging of these files.
