NAME<\/a> subuid \u2212 the subordinate uid file<\/p>\n Each line in \/etc\/subuid contains a user name and a range of subordinate user ids that user is allowed to use. This is specified with three fields delimited by colons (\u201c:\u201d). These fields are:<\/p>\n \u2022 login name or UID<\/p>\n \u2022 numerical subordinate user ID<\/p>\n \u2022 numerical subordinate user ID count<\/p>\n This file specifies the user IDs that ordinary users can use, with the newuidmap<\/b> command, to configure uid mapping in a user namespace.<\/p>\n Multiple ranges may be specified per user.<\/p>\n When large number of entries (10000\u2212100000 or more) are defined in \/etc\/subuid, parsing performance penalty will become noticeable. In this case it is recommended to use UIDs instead of login names. Benchmarks have shown speed\u2212ups up to 20x.<\/p>\n \/etc\/subuid<\/p>\n Per user subordinate user IDs.<\/p>\n \/etc\/subuid\u2212<\/p>\n Backup file for \/etc\/subuid.<\/p>\n login.defs<\/b>(5), newgidmap<\/b>(1), newuidmap<\/b>(1), newusers<\/b>(1), subgid<\/b>(5), useradd<\/b>(8), userdel<\/b>(8), usermod<\/b>(8), user_namespaces<\/b>(7).<\/p>\n subuid \u2212 the subordinate uid file <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[959],"tags":[961,1291,1690],"class_list":["post-4772","post","type-post","status-publish","format-standard","hentry","category-5-formatos-de-ficheros","tag-961","tag-man5","tag-subuid"],"gutentor_comment":0,"_links":{"self":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/4772","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/comments?post=4772"}],"version-history":[{"count":0,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/4772\/revisions"}],"wp:attachment":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/media?parent=4772"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/categories?post=4772"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/tags?post=4772"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
